The Cyber Power is - like some other Pro's Pro strings - a good value for the price. It provides good control and touch if you hit the ball cleanly. If you have arm problems I would not recommend any polyester string anyway (except for the Polyfibre Poly-Hightec).

Genius string for allround and defensive players. Superb power at low racquet speed. Hard to control for absolute hardhitters. But it helps to get out of defensive situations during play. Particularly at the volley it provides great feel. Highly recommendable!
